Superstar-in-the-making Hunter Hayes debuted his new song 'I Want Crazy' at the 2013 ACMs on Sunday (April 7), and the knock 'em dead performance showed everyone why Hayes is going to be around for a long, long time to come.

The words 'Let's be crazy' were scribbled across the pick guard of the guitar on which Hayes was knuckling down. He was surrounded by huge balloons with his name and the lyrics printed on them, a few of which he booted into the crowd. Hayes reminds us of a young Keith Urban with the way he handles his guitar.

The performance of 'I Want Crazy' ended with confetti… but it was a false ending, as Hayes welcomed R&B icon and legend Stevie Wonder to the stage to perform with him soon after his first song ended.

The May-December duo from different generations and genres performed Wonder's 'Sir Duke' alongside one another, and it was a wonderful pairing. Wonder was playing off his younger duet partner's energy, and the camera cut to several superstars like Tim McGraw, Faith Hill and Taylor Swift rocking out.

As they finished, Hayes walked over to shake Wonder's hand, showing that not only is he talented, but he's a pro, too.
